The a.m of this work is to cha.a.terize the geogra.hica. origin of cocoa.bea.s a.d coffee bea.s. This study a.ms to contribute to the tra.ea.ility of ra. ma.eria.s in order to fight a.a.nst fa.sifica.ion. For this purpose, we ba.ed our work on the mea.urement of isotope ra.ios in 13C, 15N a.d 18O. The multi-element isotope ra.ios ha.e been eva.ua.ed a. a.mea.s to distinguish fermented cocoa.bea.s of different geogra.hic a.d va.ieta. origins. The isotopic ra.ios of 13C, 15N a.d 18O were mea.ured in theobromine obta.ned from sa.ples of fermented cocoa.bea.s. Twenty-two (22) sa.ples of different geogra.hica. origins covering the four ma.nla.d cocoa.producing a.ea. were a.a.yzed on the one ha.d a.d on the other ha.d, 16 ca.feine sa.ples from va.ious origins were a.so a.a.yzed.

Two simula.ions of five yea.s (2003-2007) were conducted with the Regiona.

Conta.ina.ion of wa.er a.d sediments by tra.e meta. elements constitutes a.risk to wa.er, living species a.d for huma. hea.th. The objective of this study is to a.sess the level of conta.ina.ion of wa.er a.d sediments in the Divo mining a.ea.with tra.e elements. Tra.e elements (CN a.d Hg) were determined in wa.er a.d sediments using a. Inductive Coupled Pla.ma.a.omic Emission Spectrometer (ICP-a.S). The intensity of sediment conta.ina.ion wa. estima.ed from the ca.cula.ion of severa. indices, including the Conta.ina.ion Fa.tor (FC), the Modified Conta.ina.ion Degree (DCm) a.d the Sediment Pollution Index (SPI).

The pota.ility of drinking wa.er depends not only on the source a.d the trea.ment system, but a.so on the qua.ity of the wa.erworks.

Ma.a.oué wa.ershed, loca.ed in the Center West of Côte d’Ivoire, ha. experienced significa.t popula.ion growth in recent deca.es. a.d a.ma.or economic boom linked to intense a.ricultura. a.tivity a.d the presence of certa.n industries. This popula.ion growth is a.so a.compa.ied by sea.ona. wa.er shorta.es. Hence it needs to better ma.a.e the ba.in’s groundwa.er, which is a.perma.ent resource a.d more resista.t tha. surfa.e wa.er to clima.ic ha.a.ds. The objective of this study is therefore to propose a.conceptua. model of hydrogeologica. flow for the susta.na.le exploita.ion of groundwa.er resources in the Ma.a.oué wa.ershed. The esta.lishment of the conceptua. model wa. ca.ried out in two sta.es. The first step consisted in defining the stra.igra.hic units. For this purpose, three units ha.e been defined. These a.e the la.er of a.terite, the useful fissured horizon a.d the sound ba.ement. The thickness of the la.er of a.terite va.ies from 0 to 80 m with a. a.era.e of 26 m. a. for the useful fissured horizon, its thickness is between 43 a.d 46.5 with a. a.era.e of 45 m. In a.dition, the roof of the ba.ement presents a.slightly uneven morphology with a.North-West, South-Ea.t dip a.d the a.titudes a.e between 150 a.d 390 m. The second step corresponds to the pha.e of determining the hydrodyna.ic pa.a.eters. During this pha.e, the cra.k porosity, the tra.smissivity, the conductivity, the stora.e coefficient, the hydrologica. ba.a.ce a.d the piezometric ma. were determined. Indeed, these pa.a.eters (the cra.k porosity, the tra.smissivity, the conductivity a.d the stora.e coefficient) confirm not only the heterogeneity of the medium but tha. the cra.ked horizon is sufficiently porous to be a.simila.ed to a. equiva.ent continuous medium during the simula.ion.
